    Tumour metabolism has become a novel factor targeted by personalised cancer drugs. This research evaluated the prognostic significance of metabolism-related genes (MRGs) in ovarian serous cystadenocarcinoma (OSC).

    MRGs in 379 women surviving OSC were obtained using The Cancer Genome Atlas (TCGA) database. Then, several biomedical computational algorithms were employed to identify eight hub prognostic MRGs that were significantly relevant to OSC survival. These eight genes have important clinical significance and prognostic value in OSC. Subsequently, a prognostic index was constructed. Drug sensitivity analysis was used to screen the key genes in eight MRGs. Immunohistochemistry (IHC) staining confirmed the expression levels of key genes and their correlations with clinical parameters and prognosis for patients.

    A total of 701 differentially expressed MRGs were confirmed in women with OSC by the TCGA database. The random walking with restart (RWR) algorithm and the univariate Cox and lasso regression analyses indicated a prognostic signature based on eight MRGs (i.e., ENPP1, FH, CYP2E1, HPGDS, ADCY9, NDUFA5, ADH1B and PYGB), which performed moderately well in prognostic predictions. Drug sensitivity analysis indicated that PYGB played a key role in the progression of OSC. Also, IHC staining confirmed that PYGB has a close correlation with clinical parameters and poor prognosis in OSC.

    The results of the present study may help to establish a foundation for future research attempting to predict the prognosis of OSC patients and to characterise OSC metabolism.

    The Covid-19 pandemic is testing the resistance of health systems, the preservation of health professionals is a priority in processes of this type. The professionals’ exposure to suspicious contacts often requires their confinement. The objective was to know the epidemiological characteristics of the primary care professionals who required confinement.

    The research was carried out in the North Metropolitan Primary Care Area of Barcelona, from February 17 to May 3, 2020. 1,418 professionals who required confinement due to the epidemic by Covid-19 participated. The reasons for confinement, symptomatology, the confinement time and the results of PCR tests results were recorded. Univariate descriptive analysis was performed.

    78.8% of the professionals were women and the mean age was 45.2 years. 67.8% were doctors and nurses, in the remaining 32.2% there were different healthcare and non-care professionals. 64.1% of the sample presented symptoms compatible with Covid-19. Participants described multiple symptoms during confinement. 1,050 diagnostic RT- PCR tests were performed, being positive in 323 cases, of which 33 were in asymptomatic people.

    The impact of the epidemic by Covid-19 is anticipated in health personnel compared to the general population. AZD3514 The distribution of symptoms in healthcare professionals is similar to that of other studies in the general population. Of the total number of professionals requiring isolation, 22.7% confirmed the diagnosis.

This study investigated the relationship between neck pain and cervical Modic changes, and risk factors for neck pain (NP). MATERIAL AND METHODS This study included 168 patients diagnosed with cervical spondylotic myelopathy between February 2013 and April 2017. Basic patient information about demographic and lifestyle variables was obtained from medical records. Radiographic images provided cervical alignment (C2-C7 Cobb), T1 slope and C7 slope. All patients underwent MRI to evaluate the presence of Modic changes. Univariate analyses identified the variables as potential factors. Variables with a p less then 0.10 were included in the multivariate logistic regression analysis models. P-values less then 0.05 were statistically significant. RESULTS Only 93 patients (55.4%) had NP. Modic changes in patients with NP were significantly higher than those without Modic changes (p=0.002). Eighty-five patients had Modic changes types I, II, III; 41 (48.2%), 29 (34.1%), 15 (17.6%), respectively. The distribution of these Modic changes varied with NP (p less then 0.001). Type I Modic changes were seen with NP more frequently than other types of Modic changes. Univariate and multivariate analyses showed that age (odds ratio , 1.09; 95% confidence interval , 1.02-1.16) and Modic changes (OR 1.25; 95% CI, 0.09-1.46) were significant independent factors for NP. CONCLUSIONS In cervical spondylosis, age and Modic changes were associated with NP. Modic change type I is more likely to occur with NP.Infectious haematopoietic necrosis virus (IHNV) is the causative agent of infectious haematopoietic necrosis (IHN), a disease of salmonids responsible for great economic losses. The disease occurs in most parts of the world where rainbow trout is reared but has not been previously reported in North Macedonia. In this study, 150 pooled samples in total, each consisting of organ mix of 10 freshly killed rainbow trout Oncorhynchus mykiss, were collected from 50 trout farms by the Food and Veterinary Agency of North Macedonia as part of the annual surveillance plan for IHN and viral haemorrhagic septicaemia (VHS) control. Screening of samples was done by cell culture and real-time RT-PCR (qRT-PCR). All 150 tested samples were VHS virus (VHSV) qRT-PCR negative. Two samples from different trout farms were IHNV qRT-PCR positive. On cell culture, 1 IHNV qRT-PCR positive sample caused cytopathic effect after 2 passages on EPC cells. The virus, isolated from an asymptomatic rainbow trout fry, was identified by qRT-PCR and designated as MAKIHNV1.
